Troon Group — 201 Stock Road, Bullsbrook ("Northern Gateway Industrial Park")
City of Swan (North-East Corridor) · $79.8M settled Aug 2026 · ~130 industrial lots · 6.40 MW full build · Intercept: T-36 to T-24m
| Owner / SPV Proof |
Troon Group (Tom McInerney, Managing Director, Ballarat/Melbourne) via two sequential SPVs incorporated on the exact same day (07 May 2026): TROON BULLSBROOK INVESTMENTS NO.1 PTY LTD (ACN 697 850 221) and 201 STOCK ROAD PTY LTD (ACN 697 851 586 — Corporate Trustee for Unit Trust). ASIC VERIFIED $79.8M (~$80M) purchase settled August 2026. |
| Size & Lot Yield |
176.0–180.0 ha gross (~135 ha net developable industrial land) yielding ~130 general & heavy industrial lots along the freight corridor. |
| Est. Electrical Load |
6.40 MW diversified maximum demand (~7.11 MVA at 0.90 PF) and 25.60 GWh/yr energy consumption (calibrated at 0.036 MW/gross ha to match ERA industrial licence filings). CALIBRATED LOAD Sits dead-centre in the 4–10 MW Goldilocks zone. |
| Stage & Intercept Window |
Phase 2–3 (Post-Settlement / Pre-WAPC Subdivision Lodgement · T-36 to T-24 Months). Land settled Aug 2026; zero subdivision lots lodged on SLIP yet. Catching the developer before Western Power UDS feeder quotes are locked in. |
| Corridor Bolt-On Upside |
Sits 6 km south of Lester Group's Muchea Industrial Park and adjacent to Mirvac's 'Darling' Bullsbrook South (5–8 MVA) and Providence Lifestyle Bullsbrook (237 homes, ~1.2 MW), enabling a 12.6–15.6 MW Bullsbrook–Muchea Corridor Hub. |
THE GRID PROBLEM (WHY CONVENTIONAL WESTERN POWER SUPPLY FAILS HERE)
- Regulator-Proven 22 kV Feeder Starvation: While Muchea Zone Substation (MUC) shows 5–15 MVA nominal transformer capacity on paper until 2030, Zenith's own 7 Jan 2026 ERAWA EDL10 amendment for Muchea Industrial Park (6 km north) proved that Western Power lacks 22 kV distribution feeder capacity in this corridor, stalling industrial estates.
- The Historical Structure Plan Smoking Gun (<2 MVA Local Line): The historical Bullsbrook Industrial Structure Plan (prepared with Cossill & Webley) explicitly recorded that the existing Stock Road 22 kV line has less than 2.0 MVA spare capacity, and full build requires trenching a 19 km dedicated 22 kV feeder from Muchea Zone Substation.
- Mandatory 2026/27 C&I Rooftop Solar Export Trap: Across 130 industrial warehouses, mandatory rooftop solar (3–5 MWp+) will saturate the weak local 22 kV voltage regulator at midday unless absorbed by an on-site central BESS.
WHY A PRIVATE MICROGRID WINS HERE
- Single Counterparty ($80M Skin in the Game): One private Victorian developer owns the entire 180 ha parcel and needs to release Stage 1 industrial titles fast to service debt/equity on an $80M land purchase.
- Out-of-State Developer Blind Spot: Because the buyer is headquartered in regional Victoria (Ballarat/Melbourne), they do not have entrenched WA Western Power workarounds and need a local turnkey BOO power partner.
- Zero-CapEx Headworks Rescue: Instead of waiting 3–4 years and paying $8M–$12M to trench 19 km of 22 kV cable from the substation, a 3.5 MVA skinny boundary connection + 4.5 MWp Solar + 3.5 MW / 10 MWh BESS energises Stage 1 in 12–15 months.
- 95% Retail/Network Annuity + 5% WEM IRCR Credits: 130 C&I tenants pay 20–25% below the $536k/2GWh bundled grid benchmark behind a single master boundary meter, while the BESS captures ~$756k/yr in WEM Reserve Capacity (IRCR) credits.
CLOSEST ZENITH PRECEDENT
Muchea Industrial Park (EDL10/ERL33 Amendment, approved 7 Jan 2026) & Peel Business Park (EDL7/ERL28): Almost identical hectarage (180 ha vs. Muchea's 145 ha and Peel Phase 1's 120 ha) and identical 22 kV radial feeder bottleneck.
WHO TO APPROACH (VERIFIED CHANNELS)
- Primary Decision-Maker: Tom McInerney (Managing Director, Troon Group) — HQ:
(03) 5331 7777 | info@troongroup.com.au.
- Warm Engineering Channel: Cossill & Webley (Mark Cundill / settling civil team,
(08) 9422 5800) — named on the historical 201 Stock Rd structure plan and already Zenith's #1 partner on Peel (EDL7) and Eglinton (EDL10).
- Selling / Advisory Channel: JLL / Burgess Rawson Perth Industrial Capital Markets team who brokered the $79.8M transaction.
LICENCE & REGULATORY ROUTE
Direct annexation onto existing EDL10/ERL33 (following the 7 Jan 2026 ERAWA precedent that added Muchea Industrial Park just 6 km away) or standalone EDL/ERL.
Key Risk
Troon is early in its post-settlement masterplanning; if approached too late (after they lodge a standard Western Power 7 MVA feeder inquiry), they will lose 9–12 months waiting for the utility shock letter.
Next Step
Call Cossill & Webley ((08) 9422 5800) to confirm if they are retained by Troon on 201 Stock Rd, and reach out directly to Tom McInerney at Troon Group ((03) 5331 7777) with a Muchea-style turnkey microgrid brief.

1. BOTTOM-UP ELECTRICAL LOAD & FEEDER DEFICIT DERIVATION
Step 1 — Gross Hectare to Diversified MW Load (ERA EDL10 Industrial Benchmark)
176.0–180.0 ha gross × 0.036 MW/gross ha = 6.40 MW diversified peak demand (7.11 MVA @ 0.90 PF)
Matches Zenith's own ERAWA EDL10 load forecast density for Muchea Industrial Park (~5.0 MW across 140 ha).
Step 2 — Annual Estate Energy Consumption (GWh/yr at 45.7% Industrial Load Factor)
6.40 MW peak × 4,000 equivalent full-load hrs/yr = 25.60 GWh/yr (12.80 × the 2.0 GWh Slide 4 C&I reference unit)
Equivalent to ~130 light/heavy fabrication, logistics, transport depot, and cold-storage workshops averaging ~197 MWh/yr each.
Step 3 — Western Power 22 kV Feeder Deficit & Boundary CMD Sizing
7.11 MVA Ultimate Demand − 2.00 MVA Existing Stock Rd Feeder Limit = 5.11 MVA Feeder Deficit
Instead of paying $8M–$12M to trench 19 km of new 22 kV cable from Muchea ZS, Zenith bridges the estate behind a 3.50 MW (3.89 MVA) skinny boundary meter + 3.50 MW / 10.0 MWh BESS + 4.50 MWp Solar PV.
Step 4 — Stage-by-Stage Ramp Schedule (Years 1 to 5)
Yr 1 (Stage 1, 30 lots): 1.50 MW (6.0 GWh) → Yr 3 (75 lots): 3.70 MW (14.8 GWh) → Yr 5 (130 lots): 6.40 MW (25.6 GWh)
Modular BESS blocks (2 × 5.0 MWh containers) scale in lockstep with lot settlements so CapEx never outruns tenant connections.
